Short answer: for the old NC45 spf select try Urban Decay 8.0 with the Brightening Primer - SO MUCH BETTER than Mac. Just found Urban Decay and THANK GOD! I look FLAWLESS! I never looked this good with MAC so now ALL my products are from URBAN DECAY. I'm loyal to you if you're loyal to me so the Funny thing is I would have still been a MAC girl if they hadn't screwed up and got rid of my shade. I get NOTHING from them now.
